- Some of the many causes of hearing loss include: 1  hereditary disorders – some types of hearing loss are hereditary, which means parents pass on affected genes to their children. In most cases, hereditary hearing loss is caused by malformations of the inner ear.

- Hereditary deafness is hearing loss that is inherited or passed down from parents to their children. This type of hearing loss may be inherited from one or both parents who may or may not have a loss of hearing themselves. Hereditary material or genes are located on chromosomes which are found in each cell of the body.efective genes can also pass along traits such as hearing loss or speech and language disorders. The hereditary hearing loss that results from defective genes may be syndromic or nonsyndromic, dominant or recessive. Syndromic hearing loss is associated with specific traits additional to hearing impairment.

Developmental psychology Alternatively, acquired deafness may be due to damage to the ear due to noise or from other conditions. Congenital deafness may or may not be genetic. In non-genetic causes, congenital deafness may be due to a condition or infection to which the mother was exposed during pregnancy, such as the rubella virus. Alternatively, congenital hearing loss may be associated with certain other characteristic findings.

Description The prognosis of childhood hearing loss is variable and depends on the type of hearing loss, age of the child at time detection and intervention, and the presence of risk factors, such as developmental delays, syndromic hearing loss, and other sensory impairment (e.g., blindness).

- Other causes include intellectual disability and autism. A person can be born mute, or become mute later in life due to injury or disease. The prevalence of mutism from all causes is on the order of 0.8 persons per 1000. Trauma or injury to the Broca's area of the brain can cause muteness.

- The movement of these bones sends sound waves across the middle ear to the inner ear. The inner ear sends the sound messages to the brain. But if the middle ear has fluid in it, then the eardrum and the bones cannot move well. This could cause your child to have trouble hearing.

Syndromic and Non-syndromic as Types of Hereditary Deafness The primary cause of hearing impairment can still be traced to genetics. The strange aspect of this fact is that a child may inherit deafness even when both parents suffered no hearing loss. This is due to the two types of hereditary deafness-syndromic and nonsyndromic.f deafness is due to problem in the inner ear, then it is called sensorineural hearing loss. Hearing impairment can also be classified according to when it happened. If the deafness in children happened before the development of language skills, then it is called prelingual deafness.

Causes of Hearing Loss at Birth The following are reasons that may cause a baby to have a hearing loss at the time of birth or as the baby grows: 1  Low Apgar score – a score of 0-4. 2  Low birth weight – weighing less than 1,500 grams or 3.3 lbs at birth.  Infections – of both the baby and the pregnant mother can cause hearing loss for the baby.

- Deaf children who have motor or sensory. impairments in addition to deafness, such as poor. vision or cerebral palsy, perform less well as a group. than deaf children without additional impairments. (Allen, 1989). Together these data indicate that the. academic achievement of deaf students is predicted.

Hearing loss Hearing loss, also known as hearing impairment, is a partial or total inability to hear. A deaf person has little to no hearing. Hearing loss may occur in one or both ears. In children hearing problems can affect the ability to learn language and in adults it can cause work related difficulties. In some people, particularly older people, hearing loss can result in loneliness. Hearing loss can be temporary or permanent. Hearing loss may be caused by a number of factors, including: genetics, ageing, exposure to noise, some infections, birth complications, trauma to the ear, and certain medications or toxins. A common condition that results in hearing loss is chronic ear infections. Certain infections during pregnancy such as rubella may also cause problems. Hearing loss is diagnosed when hearing testing finds that a person is unable to hear 25 decibels in at least one ear.

Help for Parents of Children With Hearing Loss The causes of hearing loss in children include: Otitis media. This middle ear infection happens often in young children because their Eustachian tubes (the tubes that connect the middle ear to the nose) are not fully developed. Fluid builds up behind the eardrum and can become infected.

Cochlear Implants Hearing loss is caused by a number of different problems that occur either in the hearing nerve or parts of the middle or inner ear. The most common type of deafness is caused by damaged hair cells in the cochlea, the hearing part of the inner ear. Normally, hair cells stimulate the hearing nerve, which transmits sound signals to the brain. When hair cells stop functioning, the hearing nerve remains unstimulated, and the person cannot hear.

Hearing Loss in Dog (Canine Deafness) Definition of Deafness. Deafness is the complete or partial lack of hearing. It can be hard to assess in dogs, because they can’t discuss their hearing difficulties. Deafness in one ear is especially difficult to detect. Anything that injures the ear canal, ruptures the ear drum or interferes with the tiny bones inside the ear can contribute to deafness, including infections, tumors, waxy build-up, repeated exposure to gunfire and nerve degeneration associated with old age.

Sensorineural Hearing Loss Sensorineural hearing loss is due to damage to the sensory hair cells in the cochlea of the inner ear, preventing nerve cells from sending complete signals to the brain. Causes Causes of sensorineural hearing loss include: Congenital/Hereditary – Many sufferers are born with sensorineural hearing loss or are predisposed to the condition through genetics. Congenital causes can include lack of cochlear development and congenital rubella syndrome.

Causes of Hearing Loss in Children Otitis media is the most frequently diagnosed disease in infants and young children (1). Seventy-five percent of children experience at least one episode of otitis media by their third birthday. Almost one-half of these children will have three or more ear infections during their first 3 years of life (2).t the other extreme are repeated bouts with infection, thick glue-like fluid and possible complications such as permanent hearing loss. Fluctuating conductive hearing loss nearly always occurs with all types of otitis media. In fact it is the most common cause of hearing loss in young children.

Deafness Caused by Disease Some people are born deaf while others obtain hearing loss due to affliction with disease. Many members of the deaf community had hearing at one point, only to lose it later in life. Some of the most prevalent diseases known to cause deafness include meningitis, Meniere'ménière S, Disease Alport, syndrome, rubella and. mumps

A child with microtia and atresia Unilateral deafness describes deafness that affects one ear. This is often associated with unilateral (single-sided) microtia and atresia. Unilateral deafness is often referred to as 'one-sided hearing loss' or 'single-sided deafness'. One ear has a normal level of hearing, and most children with unilateral deafness manage very well in most situations.

Types of hearing loss Causes. Repeated exposure to loud noise or sounds might be putting you at risk for sensorineural hearing loss! If a child is born with sensorineural hearing loss, it is most likely due to a genetic syndrome or an infection passed from mother to fetus inside the womb, such as toxoplasmosis, rubella or herpes. When sensorineural hearing loss develops later in life, it can be caused by a wide variety of triggers, including: 1  Deterioration caused by age (presbycusis). 2  Blood vessel diseases. 3  Auto-immune diseases.

SensorineuÂral hearing loss Sensorineural hearing loss The causes of sensorineural hearing loss are varied but can be generally put into two categories: congenital and acquired. Congenital hearing loss is present at birth and is the most common problem seen in newborn babies. It can be either inherited or caused by abnormal development in the fetal stages of life.
